^aRichness is equal to the number of LH-PCR or FAME peaks. 

^bEvenness is equal to diversity/ln (richness). 

^cDiversity (Shannon index) (H) was calculated as follows: H = −Σp_iln(p_i), where p_i is the relative abundance of a given LH-PCR or FAME peak. 

^dValues are means ± standard deviations (n = 4). For each index, different letters indicate that values for different sites determined by the same method were significantly different (P < 0.05), as determined by one-way analysis of variance and least significant difference.
